Assessing Planet Fitness (PLNT) Valuation After $750 Million Debt Refinancing and Capital Structure Shift

Planet Fitness (PLNT) just locked in $750 million of new senior secured notes, a refinancing move designed to tidy up older debt, bolster reserves, and leave room for potential share buybacks.

See our latest analysis for Planet Fitness.

The refinancing headlines cap a steady stretch for Planet Fitness, with the latest share price at $109.15 and a 90 day share price return of 6.40% alongside a three year total shareholder return of 45.09%, suggesting momentum is gradually rebuilding.

If this kind of balance sheet reshaping has you rethinking your watchlist, it might be worth exploring fast growing stocks with high insider ownership for other stocks where insiders are backing the growth story with their own capital.

With earnings still growing double digits and the stock trading about 18% below analyst targets, investors now face a key dilemma: Is Planet Fitness quietly undervalued, or is the market already baking in years of future gains?

Another View: Valuation Looks Rich on Earnings

Step away from the narrative of fair value and the earnings lens tells a tougher story. Planet Fitness trades on a 44x price to earnings ratio versus 28.1x for peers and a 23.8x fair ratio, implying the market is already paying up for perfection. What happens if growth simply moderates?
